Does anyone know of a good shop that can do a gear swap on new gm 4x4 pickup trucks? Orange county, rockland county or Northern NJ area. A friend and I are both looking for a good shop to do this that knows what there doing with gear swaps. I have a 2018 GMC Sierra 1500 6.2 with 3:23 gears that i would like to change to 3:73 gears.

Thanks Joe
